RESUMO

UNLABELLED: Critical illness has a major impact on the nutritional status of both children and adults. A retrospective study was conducted to evaluate the incidence of hospital malnutrition at a pediatric tertiary intensive care unit (PICU). Serum concentrations of IL-6 in subgroups of well-nourished and malnourished patients were also evaluated in an attempt to identify those with a potential nutritional risk. METHODS: A total of 1077 patients were enrolled. Nutritional status was evaluated by Z-score (weight for age). We compared mortality, sepsis incidence, and length of hospital stay for nourished and malnourished patients. We had a subgroup of 15 patients with severe malnutrition (MN) and another with 14 well-nourished patients (WN). Cytokine IL-6 determinations were performed by enzyme-linked immunosorbent assay. RESULTS: 53% of patients were classified with moderate or severe malnutrition. Similar amounts of C- reactive protein (CRP) were observed in WN and MN patients. Both groups were able to increase IL-6 concentrations in response to inflammatory systemic response and the levels followed a similar evolution during the study. However, the mean values of serum IL-6 were significantly different between WN and MN patients across time, throughout the study (p = 0.043). DISCUSSION: a considerable proportion of malnourished patients need specialized nutritional therapy during an intensive care unit (ICU) stay. Malnutrition in children remains largely unrecognized by healthcare workers on admission. CONCLUSIONS: The incidence of malnutrition was very high. Malnourished patients maintain the capacity to release inflammatory markers such as CRP and IL-6, which can be considered favorable for combating infections On the other hand, this capacity might also have a significant impact on nutritional status during hospitalization.

RESUMO

OBJECTIVE: To study the effects of recombinant human erythropoietin (rHuEpo) in preterm newborns (PTNs) with serious infectious diseases. METHODS: A not randomized case-control study was carried out in 34 preterm newborns with diagnosis of serious infectious pathologies, gestational age up to 35 weeks, birth weight less than 1500 g and clinical stability. Newborns selected for treatment with rHuEpo received 400 U/kg erythropoietin ss, subcutaneously twice a week. Oral iron supplementation was initiated when the levels of serum ferritin were lower than 60 mcg/l. The study was continued for six weeks or until the patient was discharged from the hospital. Erythropoiesis, granulopoiesis, thrombocytopoiesis, the need for transfusions and the occurrence of new episodes of infectious disease were analyzed. RESULTS: In the treated group there was a significant increase in the number of reticulocytes, although there was no statistically significant difference between the groups with regard to the number or volume of transfusions. There was no significant difference in neutrophils and platelet values. CONCLUSION: The use of rHuEpo, 800 U/kg/week, in PTNs with infectious diseases was effective in inducing erythropoiesis, without significant changes in the number of neutrophils or platelets. This strategy, and the accurate control of the blood collected for laboratory exams, may be beneficial for prevention of the anemia in PTNs with serious infectious diseases.

RESUMO

OBJECTIVE: The objective of this study was to evaluate the ratio of dead space to tidal volume (VD/VT) as a predictor of extubation failure of children from mechanical ventilation. METHODS: From September 2001 to January 2003 we studied a cohort consisting of all children (1 day-15 years) submitted to mechanical ventilation at a pediatric intensive care unit who were extubated and for whom pre-extubation ventilometry data were available, including the VD/VT ratio. Extubation success was defined as no need for any type of ventilatory support, invasive or otherwise, within 48 hours. Patients who tolerated extubation, with or without noninvasive support, were defined as success-R and compared with those who were reintubated. Statistic analysis was based on a VD/VT cutoff point of 0.65. RESULTS: During the study period 250 children received mechanical ventilation at the pediatric intensive care unit. Eighty-six of these children comprised the study sample. Twenty-one children (24.4%) met the criteria for extubation failure, with 11 (12.8%) of these requiring non-invasive support and 10 (11.6%) reintubation. Their mean age was 16.8 (+/-30.1) months (median = 5.5 months). The mean VD/VT ratio for all cases was 0.62 (+/-0.18). Mean VD/VT ratios for patients with successful and failed extubations were 0.62 (+/-0.17) and 0.65 (+/-0.21) (p = 0.472), respectively. Logistic regression failed to reveal any statistically significant correlation between VD/VT ratio and success or failure of extubation (p = 0.8458), even for patients who were reintubated (p = 0.5576). CONCLUSIONS: In a pediatric population receiving mechanical ventilation due to a variety of etiologies, the VD/VT ratio was unable to predict the populations at risk of extubation failure or of reintubation.

RESUMO

OBJECTIVE:: To analyze the frequency of extubation failure in premature infants using conventional mechanical ventilation (MV) after extubation in groups subjected to nasal intermittent positive pressure ventilation (nIPPV) and continuous positive airway pressure (nCPAP). METHOD:: Seventy-two premature infants with respiratory failure were studied, with a gestational age (GA) ≤ 36 weeks and birth weight (BW) > 750 g, who required tracheal intubation and mechanical ventilation. The study was controlled and randomized in order to ensure that the members of the groups used in the research were chosen at random. Randomization was performed at the time of extubation using sealed envelopes. Extubation failure was defined as the need for re-intubation and mechanical ventilation during the first 72 hours after extubation. RESULTS:: Among the 36 premature infants randomized to nIPPV, six (16.6%) presented extubation failure in comparison to 11 (30.5%) of the 36 premature infants randomized to nCPAP. There was no statistical difference between the two study groups regarding BW, GA, classification of the premature infant, and MV time. The main cause of extubation failure was the occurrence of apnea. Gastrointestinal and neurological complications did not occur in the premature infants participating in the study. CONCLUSION:: We found that, despite the extubation failure of the group of premature infants submitted to nIPPV being numerically smaller than in premature infants submitted to nCPAP, there was no statistically significant difference between the two modes of ventilatory support after extubation.

RESUMO

This study compared concentrations of total protein, lysozyme, and immunoglobulins (IgA, IgG, IgM) in samples of colostrum (n=101) obtained from mothers of infants<32 weeks, 32 to 36(6) 7 weeks, and >or=37 weeks gestational age, both before and after pasteurization. Total protein was measured by refraction index, lysozyme by the lysoplate method, and immunoglobulins through the radial immunodiffusion technique. The total protein concentration was greater in colostrum of the <32 weeks and 32 to 36(6) 7 weeks categories compared to full-term (P<.001), while concentrations of lysozyme and IgM were similar. IgA concentrations were higher in the <32 weeks group compared to the full-term and similar to the 32 to 36(6) 7 weeks group (P<.05). The IgG was higher in the <32 weeks category compared to 32 to 36(6) 7 weeks, and both were similar to the full-term (P<.05). Pasteurization significantly decreased all of the factors analyzed.

RESUMO

The objectives of this study were to determine the incidence of infection by respiratory viruses in preterm infants submitted to mechanical ventilation, and to evaluate the clinical, laboratory and radiological patterns of viral infections among hospitalized infants in the neonatal intensive care unit (NICU) with any kind of acute respiratory failure. Seventy-eight preterm infants were studied from November 2000 to September 2002. The newborns were classified into two groups: with viral infection (Group I) and without viral infection (Group II). Respiratory viruses were diagnosed in 23 preterm infants (29.5%); the most frequent was respiratory syncytial virus (RSV) (14.1%), followed by influenza A virus (10.2%). Rhinorrhea, wheezing, vomiting and diarrhea, pneumonia, atelectasis, and interstitial infiltrate were significantly more frequent in newborns with nosocomial viral infection. There was a correlation between nosocomial viral infection and low values of C-reactive protein. Two patients with mixed infection from Group I died during the hospital stay. In conclusion, RSV was the most frequent virus in these patients. It was observed that, although the majority of viral lower respiratory tract infections had a favorable course, some patients presented a serious and prolonged clinical manifestation, especially when there was concomitant bacterial or fungal infection.

RESUMO

OBJECTIVE: To analyze the usefulness of determining the cerebrospinal fluid (CSF) levels of tumor necrosis factor-alpha (TNF-alpha), interleukin-1beta (IL-1beta) and interleukin-6 (IL-6) for the early diagnosis and evaluation of the prognosis of neonatal meningitis. METHOD: We studied 54 newborn that underwent lumbar puncture. Thirty patients had meningitis and 24 were the control group. CSF and sera were obtained at the moment of suspicion of meningitis and stored at -70 degrees C. Cytokines were performed by enzyme-linked immunosorbent assay method. RESULTS: CSF cytokines were detected in all the newborn with meningitis. TNF-alpha was detected in the CSF in 63.3% of the neonates, IL-1beta in 73.3% and IL-6 in 96.6%. The CSF levels were significantly higher than serum in neonates with meningitis. There was no correlation between the CSF levels of cytokines and neurologic complications. CONCLUSION: The detection of TNF-alpha, IL-1beta and IL-6 in the CSF is of great value in order to achieve a early diagnosis of neonatal meningitis. Among the three cytokines analyzed, IL-6 was the best indicator of meningeal inflammation.

RESUMO

UNLABELLED: The vertical transmission of HIV (Human Immunodeficiency Virus) has become the main target of prophylactic Zidovudina (AZT) therapy during gestation, parturition as well as for the newborn. BACKGROUND: To characterize the clinical and laboratory evolution of HIV exposed children. METHODS: Prospective study of 64 HIV exposed children, classified into two groups. Group A, made up of 23 pairs of mothers and newborns, who did not receive AZT; Group B, made up of 41 pairs, who received AZT at some stage of prophylaxis. RESULTS: The average maternal age was 26.8 years, the use of illicit drugs occurred in 17.2% of the pregnant women, twenty (31.3%) of the women had diseases. Between the groups there were no significant differences related to prenatal frequency of maternal illnesses, birth body dimensions and growth sequence. Both study groups presented with similar lymphocyte and blood counts. On the average, seroreversion took place at 16 months. Vertical transmission occurred in 6 children (9.3%), none of the children in the subgroup who received prophylaxis during all phases were infected. CONCLUSIONS: The prophylactic therapy with AZT during all the periods recommended and the long term follow-up of the HIV exposed children constitute one of the best strategies for prevention of the acquired immunodeficiency syndrome (AIDS) in infants.

RESUMO

UNLABELLED: Acute renal failure has a high morbidity and mortality in critically ill patients. Severe sepsis and septic shock are important risk factors for the development of acute renal failure. Low-dose dopamine (0.5 to 3 mg/kg/min) has been used for decades as a renal-protective therapy in such patients, even in the absence of any controlled study to support this concept. BACKGROUND: To Check the literature for evidences supporting the routine use of low-dose dopamine in severe sepsis and septic shock. METHODS: Systematic review of the literature, on electronic databasis (MEDLINE, EMBASE and LILACS), and handsearching. RESULTS: Only five randomized clinical trials were found, but none of them studied renal outcomes. Eight cases series studies were included on a qualitative review. Dopamine was associated with some adverse effects, such as increase in pulmonary shunting, tachyarrhythmias, and increase in pulmonary artery pressure, that were not statistically significant. Mortality also did not change with the use of dopamine. CONCLUSIONS: There are no sufficient evidences in the literature to support the routine use of low-dose dopamine as a renal protective agent in severe sepsis and septic shock.

Resumo Objetivo: analisar a frequência de falha da extubação em recém-nascidos pré-termo (RNPT) em uso de ventilação mecânica (VM) convencional após a extubação traqueal nos grupos submetidos à ventilação por pressão positiva intermitente por via nasal (nIPPV) e pressão positiva contínua em vias aéreas (nCPAP). Método: foram estudados 72 RNPT portadores de insuficiência respiratória, com idade gestacional (IG) ≤ 36 semanas e peso de nascimento (PN) > 750 g, que necessitaram de entubação traqueal e ventilação mecânica. O estudo foi controlado e randomizado a fim de garantir a aleatoriedade na escolha dos integrantes dos grupos. A randomização foi realizada no momento da extubação por meio de envelopes selados. Falha da extubação foi definida como necessidade de reentubação e ventilação mecânica durante as primeiras 72 horas após a extubação. Resultados: entre os 36 RN randomizados para nIPPV, seis (16,6%) apresentaram falha de extubação em comparação a 11 (30,5%) dos 36 RN randomizados para nCPAP. Não houve diferença estatística entre os dois grupos de estudo em relação a PN, IG, classificação do RN e tempo de VM. A principal causa de falha da extubação foi a ocorrência de apneia. Complicações gastrointestinais e neurológicas não ocorreram nos RNPT participantes do estudo. Conclusão: constatamos que no grupo dos RNPT submetidos à nIPPV, apesar da falha da extubação ser numericamente menor que nos RNPT submetidos à nCPAP, não houve diferença estatisticamente significante entre os dois modos de suporte ventilatório após a extubação.

RESUMO

PURPOSE: to describe the patterns of the gastric myoelectrical activity, pre-and postprandially, in clinically stable neonates of different gestational ages, during their first two weeks of life by means of Electrogastrography. PATIENTS AND METHODS: Electrogastrography was recorded in forty-five clinically stable neonates of different gestational ages (group I: 15 neonates of > 37 weeks, group II: 15 premature neonates of 32-37 weeks; Group III: 15 premature neonates of 28-31 weeks) receiving intermittent enteral feedings during their first two weeks of life. Electrogastrography recordings were performed for 1 hour pre-and postprandially. The Electrogastrography signal was recorded using the portable MicroDigitrapper Electrogastrography recording device and after motion artifacts were deleted, the remaining Electrogastrography data were submitted to quantitative analysis based on the "Running Spectrum Analysis". RESULTS: The percentages of normogastria, pre-and postprandially were greater than the percentages of gastric dysrythmias in all three studied groups. Furthermore, all neonates had the mean values of the Electrogastrography dominant frequency predominantly within the normogastria range, in both periods analyzed. There were no significant differences in the relative change of the Electrogastrography dominant power among the groups. CONCLUSION: This study demonstrates that the Electrogastrography patterns are similar between premature and full term neonates during the pre-and postprandial periods. The results of this study also indicate that the gastric myoelectrical activity in premature and full term neonates is immature, as compared to that described for older neonates, children and adults.

RESUMO

PURPOSE: To determine the incidence and characteristics of nonimmune hydrops fetalis in the newborn population. METHOD: A retrospective study of the period between 1996 and 2000, including all newborns with a prenatal or early neonatal diagnosis of nonimmune hydrops fetalis, based on clinical history, physical examination, and laboratory evaluation. The following were analyzed: prenatal follow-up, delivery type, gender, birth weight, gestational age, presence of perinatal asphyxia, nutritional classification, etiopathic diagnosis, length of hospital stay, mortality, and age at death. RESULTS: A total of 47 newborns with hydrops fetalis (0.42% of live births), 18 (38.3%) with the immune form and 29 (61.7%) with the nonimmune form, were selected for study. The incidence of nonimmune hydrops fetalis was 1 per 414 neonates. Data was obtained from 21 newborns, with the following characteristics: 19 (90.5%) were suspected from prenatal diagnosis, 18 (85.7%) were born by cesarean delivery, 15 (71.4%) were female, and 10 (47.6%) were asphyxiated. The average weight was 2665.9 g, and the average gestational age was 35 3/7 weeks; 14 (66.6%) were preterm; 18 (85.0 %) appropriate delivery time; and 3 (14.3%) were large for gestational age. The etiopathic diagnosis was determined for 62%, which included cardiovascular (19.0%), infectious (9.5%), placental (4.8%), hematologic (4.7%), genitourinary (4.8%), and tumoral causes (4.8%), and there was a combination of causes in 9.5%. The etiology was classified as idiopathic in 38%. The length of hospital stay was 26.6 +/- 23.6 days, and the mortality rate was 52.4%. CONCLUSIONS: The establishment of a suitable etiopathic diagnosis associated with prenatal detection of nonimmune hydrops fetalis can be an important step in reducing the neonatal mortality rate from this condition.

RESUMO

Foreign body aspiration (FBA) is one of leading causes of death in children, especially among those younger than 3 years of age. The inhalation of a foreign body may cause a wide variety of symptoms, and early diagnosis is highly associated with the successful removal of the inhaled foreign material. Despite the great advances in endoscopic procedures and anesthesia, a large number of difficulties and complications still result from foreign body aspiration. We describe 5 cases of serious acute complications following aspiration of foreign bodies that became lodged in the tracheobronchial tree, including pneumomediastinum, pneumothorax, total atelectasis, foreign body dislodgment, and need for thoracotomy in children admitted into our intensive care unit in 1999 and 2000; these were all situations that could have been prevented with early recognition and prompt therapeutic intervention.

RESUMO

OBJECTIVE: To evaluate the effects of 2 different doses of exogenous surfactant on pulmonary mechanics and on the regularity of pulmonary parenchyma inflation in newborn rabbits. METHOD: Newborn rabbits were submitted to tracheostomy and randomized into 4 study groups: the Control group did not receive any material inside the trachea; the MEC group was instilled with meconium, without surfactant treatment; the S100 and S200 groups were instilled with meconium and were treated with 100 and 200 mg/kg of exogenous surfactant (produced by Instituto Butantan) respectively. Animals from the 4 groups were mechanically ventilated during a 25-minute period. Dynamic compliance, ventilatory pressure, tidal volume, and maximum lung volume (P-V curve) were evaluated. Histological analysis was conducted using the mean linear intercept (Lm), and the lung tissue distortion index (SDI) was derived from the standard deviation of the means of the Lm. One-way analysis of variance was used with a = 0.05. RESULTS: After 25 minutes of ventilation, dynamic compliance (mL/cm H2O.kg) was 0.87 +/- 0.07 (Control); 0.49 +/- 0.04 (MEC*); 0.67 +/- 0.06 (S100); and 0.67 +/- 0.08 (S200), and ventilatory pressure (cm H2O) was 9.0 +/- 0.9 (Control); 16.5 +/- 1.7 (MEC*); 12.4 +/- 1.1 (S100); and 12.1 +/- 1.5 (S200). Both treated groups had lower Lm values and more homogeneity in the lung parenchyma compared to the MEC group: SDI = 7.5 +/- 1.9 (Control); 11.3 +/- 2.5 (MEC*), 5.8 +/- 1.9 (S100); and 6.7 +/- 1.7 (S200) (*P < 0.05 versus all the other groups). CONCLUSIONS: Animals treated with surfactant showed significant improvement in pulmonary mechanics and more regularity of the lung parenchyma in comparison to untreated animals. There was no difference in results after treatment with either of the doses used.

RESUMO

Critical illness has a major impact on the nutritional status of both children and adults. A retrospective study was conducted to evaluate the incidence of hospital malnutrition at a pediatric tertiary intensive care unit (PICU). Serum concentrations of IL-6 in subgroups of well-nourished and malnourished patients were also evaluated in an attempt to identify those with a potential nutritional risk. METHODS: A total of 1077 patients were enrolled. Nutritional status was evaluated by Z-score (weight for age). We compared mortality, sepsis incidence, and length of hospital stay for nourished and malnourished patients. We had a subgroup of 15 patients with severe malnutrition (MN) and another with 14 well-nourished patients (WN). Cytokine IL-6 determinations were performed by enzyme-linked immunosorbent assay. RESULTS: 53 percent of patients were classified with moderate or severe malnutrition. Similar amounts of C- reactive protein (CRP) were observed in WN and MN patients. Both groups were able to increase IL-6 concentrations in response to inflammatory systemic response and the levels followed a similar evolution during the study. However, the mean values of serum IL-6 were significantly different between WN and MN patients across time, throughout the study (p = 0.043). DISCUSSION: a considerable proportion of malnourished patients need specialized nutritional therapy during an intensive care unit (ICU) stay. Malnutrition in children remains largely unrecognized by healthcare workers on admission. CONCLUSIONS: The incidence of malnutrition was very high. Malnourished patients maintain the capacity to release inflammatory markers such as CRP and IL-6, which can be considered favorable for combating infections On the other hand, this capacity might also have a significant impact on nutritional status during hospitalization.

RESUMO

A gravidez na adolescência é um problema de saúde pública por ser considerada uma gravidez de alto risco. A incidência de prematuridade e de baixo peso ao nascer entre filhos de mães adolescentes varia dependendo da região e pais estudado. Objetivo: realizar uma análise comparativa da freqüência de prematuridade e baixo peso entre filhos de mães adolescentes e adultas. Método: estudo prospectivo comparativo de uma série de casos no qual foram incluídos 132 mães e seus recém nascidos (51 mães adolescente e 81 mães adultas) internados em dois hospitais públicos da cidade de São Paulo, no período de junho de 2005 a maio de 2006. Em relação às mães foram analisadas as seguintes variáveis: idade, raça, escolaridade, ocupação, número de gestações e de abortos, pré-natal (número de consultas), antecedentes mórbidos antes e durante o pré-natal, tipo de parto e uso de drogas lícitas e ilícitas. Em relação aos recém-nascidos foram analisados: Boletim de Apgar, sexo, peso de nascimento, idade gestacional, adequação nutricional e aleitamento materno. Resultados: A gravidez na adolescência esteve relacionada com nascimentos de crianças prematuras (16-31.4 por cento no grupo de mães adolescentes e 7-8.65 por cento no grupo de mães adultas, p= 0.01), e esta relação não foi observada com o baixo peso ao nascer (14-27.5 por cento no grupo adolescente e 16-19.8 por cento no grupo de mães adultas, p= 0.17). Não houve diferenças significantes em relação aos outros parâmetros. Conclusões: a assistência pré-natal pareceu diminuir a freqüência de baixo peso ao nascer em filhos de mães adolescentes. Não houve interferência na freqüência da prematuridade.

RESUMO

OBJECTIVE: To report a full-term newborn infant that developed a sepsis associated to meningitis caused by Neisseria meningitidis serogroup C on the 14th day of life. CASE DESCRIPTION: The patient was a term female infant, born to a mother with Systemic Lupus Erythematosus, with birth weight of 2,610g, Apgar Score 1, 4 and 8, who needed mechanical ventilation for 24 hours. On the 7th day of life, the neonate was discharged from the hospital with good overall condition. On the 15th day of life, the newborn infant presented fever and respiratory failure. The cerebrospinal fluid showed 1042 cells/mm³, with neutrophilic predominance, protein of 435 mg/dL, and glucose < 10 mg/dL. The blood and the cerebrospinal fluid cultures were positive for Neisseria meningitidis serogroup C. The neonate was hospitalized, needing mechanical ventilation and vasoactive drugs, and received 21 days of crystalline penicillin. After hospital discharge, there were no signs of neurological sequels and the infant was able to be breastfed. The case report presents a unique situation: an uncommon etiology of neonatal meningitis and favorable evolution, despite neurological sequels reported in the literature. This report emphasizes the need to prevent the premature exposure of newborn infants to pathological agents, especially if they presented birth injuries and/or are preterm, due to their lack of immunological capacity.


OBJETIVO: Relatar o caso de um recém-nascido de termo que apresentou no 14° dia de vida sepse associada à meningite, cujo agente etiológico foi a Neisseria meningitidis sorotipo C. DESCRIÇÃO DO CASO: recém-nascido de termo, cuja mãe é portadora de lupus eritematoso sistêmico, feminino, peso de nascimento de 2610g, Escala de Apgar 1, 4 e 8, sendo intubado e ventilado por 24 horas. Recebeu alta no 7° dia de vida em boas condições. No 15° dia de vida apresentou febre e desconforto respiratório. O líquido cefalorraquidiano mostrou 1042 células/mm³, com predomínio de neutrófilos, proteinorraquia de 435 mg/dL e glicorraquia < 10 mg/dL; a bacterioscopia revelou a presença de diplococos. Foi internado na Terapia Intensiva Neonatal, necessitou de ventilação mecânica e de drogas vasoativas. A hemocultura e a cultura do líquido cefalorraquidiano foram positivas para Neisseria meningitidis C. O recém-nascido foi tratado por 21 dias com penicilina cristalina. Recebeu alta hospitalar em boas condições, em aleitamento materno exclusivo e sem seqüelas neurológicas. O caso descrito apresenta como peculiaridades: etiologia incomum de meningite neonatal e evolução favorável, apesar dos relatos em literatura mostrarem seqüelas neurológicas. Destaca-se ainda, a necessidade de enfatizar a não exposição precoce do recém-nascido, especialmente se tiver tido agravos ao nascimento ou for prematuro, devido à sua inexperiência imunológica.

RESUMO

Lesões cutâneas semelhantes à acrodermatite enteropática têm sido descritas em pacientes com algumas doenças metabólicas tratadas com dietas hipoprotéicas. Esses pacientes geralmente apresentam baixos níveis séricos de alguns aminoácidos, especialmente da isoleucina. Descrevemos dois pacientes que evoluíram com lesões semelhantes às da acrodermatite enteropática durante o tratamento da doença da urina do xarope de bordo , sem deficiência do zinco. A suplementação da isoleucina determinou rápida melhora das lesões dermatológicas.


Acrodermatitis enteropathica-like cutaneous lesions have been reported in patients with some metabolic disorders that are treated with a low-protein diet. These patients usually have low blood levels of some amino acids, especially isoleucine. We describe two patients who evolved with eruptions resembling acrodermatitis enteropathica while undergoing treatment for maple syrup urine disease, without zinc deficiency. Isoleucine supplementation led to a prompt improvement of the skin disorder.
